Great handling car, right out of the box! It is a smooth drifter.Mine had traces of grease from the factory in the diffs,but everyone seems to be driving it like a latemodle. So with that being said,i tried 120,000/front,55,000/center,3,000/rear,and broke a track record two weeks ago.No more drifting here. I run approxamately a 300 ft center line hard packed clay oval,we run soft foam tires. http://ofna.com/forum/images/smiles/deal.gif

I meant 50,000 sorry There are several hobby shops around the Tampa bay area that have the diff fluid. the stuff I used was Traxxas 50,000 and ofna 120,000 . That should take some of the push out of that sprint The 20.000 in the rear diff will bring the back of the car around exiting the turns. However I am not an expert at this, but it is working for me. I broke 2 different track records last week with a hyper 8 sprint and a dirt oval pro sprint conversion. Good luck with them diffs man!
